As shown in fig. 4, the present embodiment provides a dyestripping feeding system for delivering a release film to a caudal vertebra of a dyestripping setting.

As shown in fig. 3-5, the film tearing and feeding system comprises a film tearing and flattening feeding mechanism 1 and a film feeding mechanism 2, wherein the film tearing and flattening feeding mechanism 1 is fixed on a bottom plate 4, and the film feeding mechanism 2 is horizontally and slidably connected with the bottom plate 4, i.e. the film feeding mechanism 2 can move in a back-and-forth translational manner relative to the film tearing and flattening feeding mechanism 1.

The stripping and flattening feeding mechanism 1 comprises a feeding carrier plate 10, a cantilever type feeding lock plate group 11 and a balancing weight 12.

The feed carrier plate 10 is horizontally fixed. For example, the carrier plate 10 may be fixed to the bottom plate 4 by a fixed support frame so that the bottom plate is carried and the carrier plate is moved.

The feed carrier plate 10 and the fixed support frame are fixed by means of bolts or the like.

As shown in fig. 3 to 5, the cantilever type feeding lock plate set 11 of the present embodiment has two sets, specifically, one set of the outer lower surface of the cantilever type feeding lock plate set 11 is fixed on one side of the width direction of the upper surface of the feeding carrier plate 10 and the inner lower surface of the cantilever type feeding lock plate set 11 and the upper surface of the feeding carrier plate 10 reserve a gap between the film sides, and the other set of the outer lower surface of the cantilever type feeding lock plate set 11 is fixed on the other side of the width direction of the upper surface of the feeding carrier plate 10 and the inner lower surface of the cantilever type feeding lock plate set 11 and the upper surface of the feeding carrier plate 10 reserve two gaps between the film sides.
